Ovulation question 🤪

Okay complicated question.

I started my period on the 23rd of November. We BD on the 4th, and I swear I was ovulating then because I had the egg white cm. According to apps and calculators I would’ve ovulated on the 7-9th. But I never had egg whites during those days. So question is, could I have ovulated early if I started on the 23rd? My cycle is usually 5 days periods and then 28 days till next one. I’m just so confused because the 4th was the only time I had that discharge, and I haven’t had it since
